HELP ME PLEASE QUICKLY !!!!!!!!

Answer 1

Answer:

x = 0

y = -3

Step-by-step explanation:

6x - 5y = 15

x = y + 3

We can solve the above system of equation by either substitution method or elimination method or both method.

We are going to solve by substitution method

6x - 5y = 15 -----------------------------------------------(1)

x = y + 3  ---------------------------------------------------(2)

Substitute equation  (2) in equation (1)

6(y+3) - 5y = 15

6y + 18 - 5y = 15

We can rearrange this equation

6y - 5y + 18 = 15

y + 18 = 15

subtract 18 from both-side of the equation

y + 18 - 18 = 15 -18

y = -3

Substitute for y = -3 in equation (2)

x = y+ 3

x = -3 + 3

x = 0

x = 0 and y = -3
